Gene Flow 

The exchange of genes within a population or between populations by interbreeding or migration.

It is interesting to trace the gene flow of humans.

gene pool 

A pool in which the depth of the pool indicates the health of a person's genetic background. Those who swim in the deep end of the pool generally have good and healthy genes while those who do not are over in the shallow end.

The Bush family is a prime example of a family that has been swimming in the shallow end of the gene pool for over 100 years.

Gene Simmons 

When performing cunnilingus on a girl while she is on her back, you stealthily take an extra long lick without her prior knowledge and to her surprise lick her butthole.

He went down on me last night and gave me a Gene Simmons. It felt pretty good.

Gene Pool Cocktail 

Usually found in large urban sprawls with many estates and high rises.

Most of the inhabitants are from the same DNA strand and tend to breed with each other, producing offspring that are boss eyed or have extra toes/fingers e.t.c (various mutations)
Generally, they pass their family around like party favours.

Have you ever been to Basinstoke, its like a Gene Pool Cocktail!

Gene sis 

NOT your HALF sis, or your STEP sis, but your REAL, GENUINE, GENE sis! She got ALL of her genes from the same two people you did!

The title "gene sis" is normally irrelevant, unless you are already mentioning your half sis, step sis, bridge sis, side step sis, or skip sis.

Gene Simmon's Tongue 

Anatomy as stated. His tongue has seen, touched and been places many of us have only read about it books. It is an unstoppable force of nature and should be revered and celebrated as an icon and international symbol of peace.

I'm not sure what to do this weekend, but I can guarantee that I will let Gene Simmon's Tongue be my guide!

Gene pick

A stupid, mainstream movie, that panders to the lowest common denominator and takes little thought to appreciate.

Jeff - "I just watched 'Employee of the Month' with Dane Cook and Jessica Simpson"

Josh - "Ugh....sounds like a 'Gene pick'."
